Abstract: Organic farming ensures that crops are produced in a natural bio diversified state without
loss of any productivity. Synthetic chemical usage in the tropics increases the levels of the environ-
mental and health risks associated with agriculture. Every piece of synthetic material used each day
by man to ‘improve’ agricultural productivity is either ‘polluting’ or ‘poisoning’ the environment.
Through these damages to the natural environs by man, more deaths because of serious illness has
been recorded. In this work, facts are presented and discussed on how intensive crop production
causes problems and ways of ensuring less use of these toxic synthetic chemicals in crop production,
especially in the tropical regions of the world. Furthermore, major benefits of organic farming in
crop production as well as how organic farming ensures genetic diversity preservation are discussed.
This review reveals how organic farming can reduce adverse environmental impact associated with
conventional methods of synthetic chemical usage tradition. The work concludes that practising
organic farming in the tropics would be very beneficial especially for future generations.

1. Introduction
We live in an environment that is altered in every way by human activities. Every
piece of material used each day is either been ‘polluted’ or ‘poisoned’ by humans trying to
“improve” the normal lifestyle. Therefore, it is important that we educate ourselves and
take interest in what is happening to the earth in order to preserve it.
The definition of organic farming involves the ecological production and management
approach that supports and improves biodiversity. It basically minimises the use of inputs
and maximises management procedures that ensure ecological coherence [1]. However,
Hynes [2] defined organic farming as a system of agriculture that excludes the use of
synthetic pesticides, growth hormones, antibiotics, genetically modified seeds and animal
breeds, and irradiation. Studies on organic farming have showed that the inherent benefits
include a decrease in soil erosion, less use of fossil fuel, a lesser amount of nitrate leaching,
an increase in the carbon sequestration, and little to no use of synthetic chemicals [2–5].
In the tropical regions of the world, many farmers that normally use the traditional
methods which are comparable to organic farming are now converting to modern methods
that involve the use of synthetic chemicals for economic reasons. Therefore, the objective of
this review paper is to highlight the major perceived benefits of organic farming on food
productivity especially in the tropical region of the world.
2. Modern, Intensive Crop Production Causes Many Problems
2.1. Nitrate Pollution
The use of nitrogenous fertilizers, such as urea and ammonium sulphate in the tropical
crop production, increases the acidity of the soil [6]. This leads to a high nitrate concen-
tration in the environment. Studies have shown that consumption of these high doses of
